Subject: move minio directory to 'blobs'

Part of migration from minio to seaweedfs, should be agnostic about what
our actual blobstore (S3 API) is.

+
+minio is used as an S3-compatible blob store. Initial use case is GROBID XML
+documents, addressed by the sha1 of the PDF file the XML was extracted from.
+
+Note that on the backend minio is just storing objects as files on disk.
+
+## Deploying minio Server
+
+It seems to be important to use a version of minio from at least December 2019
+era for on-disk compression to actually work.
+
+Currently install minio (and mc, the minio client) in prod by simply
+downloading the binaries and calling from systemd.
+
+## Buckets and Directories
+
+Hosts and buckets:
+
+    localhost:sandcrawler-dev
+        create locally for development (see below)
+
+    cluster:sandcrawler
+        main sandcrawler storage bucket, for GROBID output and other derivatives.
+        Note it isn't "sandcrawler-prod", for backwards compatibility reasons.
+
+    cluster:sandcrawler-qa
+        for, eg, testing on cluster servers
+
+    cluster:unpaywall
+        subset of sandcrawler content crawled due to unpaywall URLs;
+        potentially made publicly accessible
+
+Directory structure within sandcrawler buckets:
+
+    grobid/2c/0d/2c0daa9307887a27054d4d1f137514b0fa6c6b2d.tei.xml
+        SHA1 (lower-case hex) of PDF that XML was extracted from
+
+Create new buckets like:
+
+    mc mb cluster/sandcrawler-qa
+
+## Development
+
+Run minio server locally, with non-persisted data:
+
+    docker run -p 9000:9000 minio/minio server /data
+
+Credentials are `minioadmin:minioadmin`. Install `mc` client utility, and
+configure:
+
+    mc config host add localhost http://localhost:9000 minioadmin minioadmin
+
+Then create dev bucket:
+
+    mc mb --ignore-existing localhost/sandcrawler-dev
+
+A common "gotcha" with `mc` command is that it will first look for a local
+folder/directory with same name as the configured remote host, so make sure
+there isn't a `./localhost` folder.
+
+
+## Users
+
+Create a new readonly user like:
+
+    mc admin user add sandcrawler unpaywall $RANDOM_SECRET_KEY readonly
+
+Make a prefix within a bucket world-readable like:
+
+    mc policy set download cluster/unpaywall/grobid
+
+## Config
+
+    mc admin config set aitio compression extensions=.txt,.log,.csv,.json,.tsv,.pdf,.xml mime_types=text/csv,text/plain,application/json,application/xml,application/octet-stream,application/tei+xml
